Why is my editor crashing when using the wheeled blueprint?

I’m using the ewheeled blueprint to create a drivable simple cube car but UE 4 crashes when I press play. I’m using the “flying template” and there is no problem flying the saucer.

If I leave the Skeletal Mesh field free in the default properties of the wheeled blueprint it doesn’t crash, as soon as I specify the Skeletal Mesh and try to play it crashes. So it has something to do with the Skeletal Mesh.

Aha! The problem shows up when I’m using the single convex hull collision geometry option when creating a new body in physics asset. I don’t have any idea why that happens though.

Solved!

By creating a new body with only the selected bones, as seen by the picture below, the problem was solved, no more crashes. Previously I selected everything when making a new body which cause the crash.
